The phenotype of the F1 generation offsprings will be black. They will be heterozygous in nature.
<h3><u>Explanation:</u></h3>
The genes for the fur colour in horses are completely dominant and the dominant colour is black and is represented by B. The recessive colour is chestnut and is represented by t.
The genotype of the homozygous black horse is BB. and the genotype of the homozygous chestnut coloured parent is tt.
The gametes from the black parent =B.
The gametes from the chestnut parent = t.
So the genotype of the F1 offspring = Bt.
It is a heterozygous black horse because the black gene is completely dominant over chestnut gene.
Answer:
The correct answer is A the excretory system when it sends out liquid waste as urea
Explanation:
The respiratory system play an important role in the the transport of oxygen and carbon dioxide in and out of the body thus maintaining the homeostasis of oxygen carbon dioxide ratio in our body which is very very important in maintaining the normal body physiology.
On the other hand the excretory system maintaintain homeostasis by interaction with respiratory system.Excretory system helps in the removal of waste material such as urea,ammonia and uric acid from our body through urine.The accumulation of waste products can hamper the normal body physiology.Thus excretory system also helps in maintaining the homeostasis of our body.
Answer:
Enzymes are protein macromolecules. With the exception of catalytic DNA and RNA which are considered enzymes but not proteins.
They have a defined amino acid sequence, and are typically 100-500 amino acids long.
They have a defined three-dimensional structure.
Explanation:
The three-dimensional structure of proteins is the primary structure of polypeptides, secondary structures in proteins (α-helix, β-sheet), and the tertiary structure.
Primary structure
Enzymes are made up of amino acids which are linked together via amide (peptide) bonds in a linear chain. This is the primary structure. The resulting amino acid chain is called a polypeptide or protein. The specific order of amino acid in the protein is encoded by the DNA sequence of the corresponding gene.
Secondary structure
The hydrogen in the amino group (NH2) and the oxygen in the carboxyl group (COOH) of each amino acid can bond with each other by means of hydrogen bond, this means that the amino acids in the same chain can interact with each other. As a result, the protein chain can fold up on itself, and it can fold up in two ways, resulting in two secondary structures: it can either wrap round forming the α-helix, or it can fold on top of itself forming the β-sheet.
Tertiary structure
As a consequence of the folding-up of the 2D linear chain in the secondary structure, the protein can fold up further and in doing so gains a three-dimensional structure. This is its tertiary structure.
Answer: The genotype of the pea plant is Tt. T is the dorminant allele and t is recessive.
Tall is the phenotype.
Explanation:
Genotype is a genes of an individual which show the phenotype or the traits.
From the above question, the pea plant have genes of T tall and t for dwarf,because T is dorminant , it is expressed over recessive.
The genotype of the pea plant is Tt.
Phenotype is the observable or visible characteristics the organism posses which is as a result of the genotype been expressed.
The phenotype is Tall.
Yes, solid has a definite shape.
